keep (one's) shoulder to the wheel

keep (one's) shoulder to the wheel

To make a sustained, concentrated, and vigorous effort; to work very hard and diligently. After nearly being expelled my first year of college, I kept my shoulder to the wheel so that I could get as much out of my degree as possible. I know that the new deadline is tight, but if everyone keeps their shoulders to the wheel, I know we can get it done in time!See also: keep, shoulder, wheel
